Supporting Information
Overview
The LMR1901YG-M leverages original ultra-low power technology that thoroughly suppresses current increase caused by temperature and voltage changes to reduce current consumption to just 160nA (Typ.) - approximately 38% lower than that of general low power op amps. This not only extends the life of applications powered by internal batteries like electronic shelf labels, but also contributes to longer operating times for smartphones and other devices equipped with rechargeable batteries. At the same time, this low current consumption does not change over the temperature range of -40°C to +105°C - allowing stable low-power operation, even in environments where external temperatures fluctuate, including fire alarms and environmental sensors.
Other performance enhancements include 45% reduction of input offset voltage to just 0.55mV (Max. Ta=25°C) over general low-current op amps while a maximum input offset voltage temperature drift of 7µV/°C is guaranteed. This enables high accuracy amplification of sensor signals. Capable of operating from 1.7V to 5.5V supply voltage and offering rail-to-rail input/output, LMR1901YG-M is suitable for a wide variety of applications in the industrial equipment and consumer markets. ROHM’s new op amp also complies with the automotive reliability standard AEC-Q100 - ensuring stable operation even under harsh conditions such as vehicle cabins without compromising functionality.
Application Examples
• Consumer applications: smartphones, smartwatches, wearables, fire alarms, motion sensors, etc.
• Industrial equipment: electronic shelf labels (ESL), handheld measurement instruments, data loggers, environmental sensors for IoT, etc.
• Automotive systems: anti-theft sensors, drive recorders, etc.
